Slit couplings / hub clamping, feather key / cross slot / body: stainless steel / SRBS, SRBMS / SUNGIL

Promotional pricing

Clamping type slit coupling that has a low moment of inertia and is stable even at high rotations.
[Features]
・ Spring with 0 backlash and radial beam absorbs eccentricity, declination, and end play.
·A short type with high torsional rigidity and torque tolerance.
·It has identical forward/reverse rotation characteristics, requires no repairs, and has high oil and chemical resistance.
[Applications]
・ Optimal for serial drive of transmission equipment, position control / positioning table, robot system, boring, and polishing machine.
·Can be used for machining centers (machine tools), medical equipment, servo motors, and speed reducers.
